Abstract
The use of thermal power plant has shown to be important to guarantee the energy supply when there is an unfavorable hydrological period, verified by the excessive use of thermal power plant on past three years. Before the current period of water scarcity, in 2000-20001 the energy crisis had earlier revealed the vulnerability of a massive use of renewable sources only in the electrical energy matrix. However, the 10-year Energy Plan 2024 shows thermal energy power will decrease Brazilian electrical energy matrix while solar and wind power will increase. Brazil already has a strong participation of hydropower plants, and these are facing serious interruptions on operation due water shortage, caused many reasons, such as changes in the amount of rainfall and increase in electrical energy consumption. Hence, the purpose of this paper is to discuss if the alternative sources expansion in the Brazilian electrical energy matrix will guarantee energy supply for the country, even with long hydrological periods unfavorable.
